Technically I am self-employed too (I tried the employment 9-5 thing, but it was too stressful for me). Most of the reputable (ish) companies are CQC registered, or at least following CQC guidelines. This means in order to insure we work to skill level and everything is in date, we get sealed bags each shift. Some companies supply kit but allow us to carry our own too. Others require us to carry our own gear. I do carry a hold all with admin stuff in it. Mostly coffee bags, but a light fleece, spare batteries etc. My plan is to add the extras to this bag and only get them out once the situation goes past the point it no long is an issue.
